Improvement in construction of elevator-buckets

Lette/rs Patent No. 85,930, dated January 19, 1869'.

IMPROVEMENT IN CONSTRUCTION OI' ELEVATOR-BUCKETS.

To all lwhom, it 'may conce/ra Be it known that I, NnrrEMIAH Hnwnnvs, of Chicago, in the county of Cook, and State of Illinois, have invented an Improvement'in Elevator-Buckets; and I do hereby declare that the following is a-'ull, `clear, and exact description ofthe same, reference being had to the accompanying drawings, and letters marked thereon, making a part of this description, in which- Figure l is a perspective representation 'of my improved elevator-bucket.

Figure 2, a perspective view of one of the ends of the bucket.

Figure 3, a transverse central section.

The nature of the present invention consists inso improving the cast'and plate-metal elevator-bucket as to provide shoulders for the nosing-plates of the front edge to rest upon, and thus prevent them from being detached as soon as the rivets with which they are fastened become worn, and in riveting the body of the bucket to flanges, or projecting lugs, on the ends of the bucket.

To enable others to fully comprehend the construction of my invention, I have marked corresponding parts with like letters, and will now give a detailed description.

A A represent the ends of thevbucket, which, if they are cast-iron, have flanges, B B', cast solid with` them, but if made of plate-metal, have the flanges formed by l means of suitable'dics for this purpose, holes, G, being made through thetlanges, to receive the rivets with which the body, 1)', is fastened to the ends.

Thisbody is made ofshect-metal, or other suitable material, and at its upper and front edge it is strengthened by means of metal plates E F, iigs. land 3, which are placed on the opposite sides of the body, l), and clamped liriniy to it, by' means of rivets, (lr, the end-rivets passing through theilanges B', and the plate F, ttinginto recesses, S, in the ends A, hold the plates, body, and ends iirinly together. .4

These plates E F are not claimed to be new, but the manner ot' so securing them to the body D, and iianges B'- of the ends A, as to bind all of these parts tirmly together, constitutes a novel feature, not shown in any bucket of which I have knowledge.

This novelty is inademore apparent in view of the recesses S, which permit the front side of the plate F -to be placed wholly iiiside of the body I), and to rest on shoulders at the lower parts of the said recesses, thus providing a' continuous bearing for the front of `the body, without bending it, as would bemthe case if the plate F projected wholly outside of the flanges B.

that shown in thepatent for elevator-bucketsI granted to J. S. Brooks, November 24, 1863, inasmuch he uses two anges on each end, and clamps the bodyzbeends, and fastening with a nut. Further, ends made with double flanges, with grooves -between them, (like those which Brooks shows,) are .much heavier than those made by me, and the bolt, as a fastening, is very objectionable, inasmuch as it prevents the bucket from properly filling with grain, and

the side ofthe spout.

viating these diiiiculties, and I consequently use sinthe body, and, as an additional security, fasten the ends of the plates E F, body D, and anges B', with the same rivets, as shown at G, iig. 1.

I de not claim to have made wholly a new bucket, b ut have been thu's particular in this description in order to show clearly one which is made complete with my improvement.

Having thus described my invention,

Vhat I claim, and desire to secure by Letters Patent 'of the United States, is

An elevator-bucket, the endsA of which have flanges B B riveted to the body D, and have recesses S formed in their front edges, to receive and support theuoseplates E F, said plates being also riveted to the flanges, substantially as and for the purpose herein set forth.

The construction of the ends A is very diiierent from tween them by means of a bolt passing through the -as the nut with which it is fastened soon cuts through My invention is made with especial reference to obgle ilanges, made as light as possible and yet support-
